SELECTION OF PLANTS. 329 



9. HELIANTHEMUM OCYMOIDES, Basil-like Sun Rose. 



This plant requires the protection of a frame in winter, 

 or to be planted against a south wall, and covered with a 

 mat in severe weather ; but in mild weather the more it is 

 exposed the better. 



It succeeds well in a light sandy soil, or if grown in 

 pots an equal mixture of sandy loam and peat. Cuttings 

 taken off at a joint, of the young wood, and planted under 

 a hand-glass, early in the autumn, will soon strike root, 

 and will probably blow the following summer. 



It is a native of the South of Europe. 



10. CISTUS PARVIFLORUS, Small-flowered Rock Rose. 



This plant must be treated as the last Helianthemum in 

 all respects. 



It is a native of Crete. 



11. CISTUS PURPUREUS, Purple-flowered Rock Rose. 



This must be treated in the same way, and requires the 

 same soil. 



It is a native of the Levant, 



12. CISTUS HIRSUTUS, Hairy Rock Rose. 



The present plant is hardier than some of the species, 

 but requires a little protection in severe weather. It pro- 

 duces a great profusion of flowers, which continues to ex- 

 pand in succession for a long time. It requires the same 

 management, and thrives in the same soil as the last. 



It is a native of Spain.
